PATENT ELEVATED RAILWAY.

SPECIFICATION forming'part of Letters Patent No. 427,836, dated May 13, 1890.

Application filed March 6, 1890- Serial No. 842,867. (No model.)

To all whom it may concern:

Beit known that I, THOMAS C. CLARKE, of the township of Shrewsbury, in the county of Monmouth and State of New Jersey, have invented a new and Improved Elevated Railway, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved elevated railway which is simple and durable and safe in construction, contains double tracks, takes up little room in the street, and does not obstruct to a great extent passage of light and air to adjoining buildings, and can be readily utilized for carrying electric-wirev cables, &c.

The invention consists of a longitudinallyextending triangular girder, and side brackets projecting from the same at suitable intervals and serving to support the double tracks.

The invention also consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a transverse section of the improvement. Fig. 2 is a side elevation of the same with the foundation in section. Fig. 3 is a plan view of the same; and Fig. 4 is a transverse section of part of the improvement as adapted for curves, turn-outs, &c.

The improved elevated railway A is provided at suitable intervals with a concrete foundation B, in which is set, while the concrete is in a plastic state, the base 0, extending at its upper end to about the surface of the roadway, in which the elevated railway is erected. In the base 0 is set a column D, of any approved construction, slightly curved at both sides and at the upper end, as is plainly shown in Fi g. 1. The'series of columns D, held along the line of the railway, support a longitudinally-extending triangular girder E, of any approved construction, but resting with its base on the said columns, as is plainly shown in the drawings. From the angular sides of this triangular girder extend at suitable intervals brackets F, adapted to support the track-rails G, on which the cars, locomotives, &c., are to run. The brackets F may also support, by suitable means, the cable for propelling the cars in case the cable system is adopted. Along the longitudinal girder E maybe strung electric wires, cables, &c., for various .purposes, they not being in the way of the cars traveling on the track G.

The upper ends of the brackets F are slightly bent upward, and the upper ends of the several brackets on each side are connected with each other by a railing I, which forms a safeguard to prevent cars from falling oil the tracks in case of accident. Now it will be seen that the longitudinal triangular girder E permits of putting brackets F on both sides, so that the strain is equally divided and taken up by the longitudinal girder resting on the series of columns D. It will further be seen that as but a single line of columns is used they can readily be set in the center of the street between the lines of the surface-railway tracks, thus utilizing a space heretofore unoccupied, or the line of the columns maybe placed in any other position where a single line of columns is admissible.

I am aware that elevated railways with a single line of columns supporting a single track have been used, and I do not claim such construction, broadly.

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent- 1. An elevated railway comprisinga longitudinally-extending triangular girder, and side brackets projecting from the same at suitable intervals on each side and adapted to support double tracks, substantially as shown and described.

2. An elevated railway comprising a single line of columns, a longitudinal triangular girder supported on the upper ends of the said columns, and side brackets secured on each side of the said girder, placed suitable distances apart and adapted to support double tracks, substantially as shown and described. 1

3. An elevated railway comprising a line of the said triangular girder and adapted to of concrete foundations, hollow bases set in support double tracks, substantially as shown the said concrete While in the plastic state, and described.
